Abstract
602,865. Switches held set and freed mechanically and electrically. CIANCHI, A. L. Dec. 2, 1942, No. 17160. [Class 38 (v)] A control switch A<1>, or several witches in the case of a polyphase circuit, and of the character described in Specification 481,289 or 559,453, wherein the contacts are mounted on, or moved by, an armature on the approach of a permanent magnet B, has the latter mounted in a block C slidable on guides D against the action of springs E when an operating button N is depressed. The parts are retained by engagement of a catch M by a stirrup L controlled by a spring K', and adapted to be released by (1) an overload bimetal strip J<1> in any phase, or (2) a spring- controlled, manual-release member K<3>, or (3) a gravity-controlled, pivoted vane Q in an airconduit O, the flow of air in which may be produced by a motor controlled by the switch, so as to stop the motor when the flow ceases.
